There is nuance, no?

Seems that getting kicked off of trust is not the same as negative.  Sure you can do both, but if a regular hammer works to pound in a small nail, it seems to be a bit overkill, and perhaps unnecessary to use a sledgehammer to attempt to accomplish the same.

Another example.  Let's hypothesize that we had a demerit system that supplements our current merit system.  There would be three levels that are each different. I could consider that you post deserves merit or I could refrain from giving merit or I could give a hypothetical demerit.  Just because I chose to not merit such post does not necessarily mean that it rises to the level of justifying employment of a demerit.  Probably not the best examples, but I attempted to answer your suggestion that removal from DT would necessarily rise to the level of negative trust.
